Continuous monitoring done right

Continuously monitoring hydrogen and moisture levels is the first step in extending your transformers’ operational life — and implementing predictive maintenance practices. 

And when you pair the MHT410 with our robust Indigo520 transmitters giving you a readout both over a sleek WebUI, and the industrial-grade local graphical display — as well as powering the MHT410.

5-year warranty as standard

The  MHT410 is robust to the extreme. It’s why we are proud to offer it with a 5-year warranty as standard. So you can rely on it to keep going in the harshest of conditions. 

Key benefits

Measure in-situ

The MHT410 measures directly from all transformer insulation liquids — including silicon oil. No pumps or membranes are needed.

Measure in real-time

Get reliable hydrogen trend and moisture data in-real time.

Get graphical with the Indigo520

Couple your MHT410 with an Indigo520 transmitter and you can monitor your transformer right from a laptop, or the local graphical display to see data trends on site. The Indigo520 can also power the MHT410 with a single-wire solution.

Robust design, easy installation.

The MHT410’s is made to stand up to the harshest conditions: isolated inputs and outputs, EMC tolerant, and IP66 metal housing. Supplied with standard DNP3.0 and MODBUS RTU communication protocols, it makes deployment within existing communications and SCADA networks easy. The MHT410 even includes three analog outputs for your SCADA interface.

Continuous monitoring gives full visibility

“It is completely different to follow the situation continuously than to take samples every now and then. After all, electricity networks can have quite exceptional switching situations – a transformer can have very high momentary loads and at other times be used only lightly.”
